## Summary description

Noctua NF-A4x10 PWM is a compact 40 × 10 mm case fan with PWM control for precise speed regulation (1000–5000 RPM). It operates at 12 V with 0.04 A max, airflow up to 8.9 m³/h (6.6 m³/h with LNA) and noise from 19.6 dB (12.9 dB with LNA). Features an SSO bearing, low-noise adaptor, 4‑pin connector, 0.3 m cable and includes four mounting screws. Ideal for small form-factor PC cooling.

## Long description

The Noctua NF-A4x10 PWM is a premium 40x10 mm cooling fan engineered for compact systems that require efficient airflow and low noise. It features advanced aerodynamic elements including Flow Acceleration Channels, Noctua's AAO frame with Stepped Inlet Design and Inner Surface Microstructures, a reduced motor hub for increased blade area, and a high-quality SSO2 bearing. The PWM model uses Noctua's custom NE-FD1 PWM IC with Smooth Commutation Drive (SCD) for quiet automatic speed control and includes a Low-Noise Adaptor and OmniJoin adaptor set for flexible connectivity.
Advantages
The NF-A4x10 PWM delivers strong performance for its size thanks to a compact motor hub that increases blade surface area and aerodynamically optimised blade and frame designs that improve airflow and pressure while reducing vortex and intake noise. Integrated anti-vibration pads minimise vibration transmission without affecting compatibility with standard mounts. The custom PWM controller with SCD reduces switching noise at low speeds and allows the fan to stop at 0% PWM for semi-passive cooling. The package includes a Low-Noise Adaptor to lower maximum RPM, an OmniJoin adaptor set for proprietary headers, extension and Y-cables, and carries a six-year manufacturer's warranty.
Suitable for
 Small form-factor PCs and mini-ITX cases
 Compact server or network appliance cooling
 Cooling for heatsinks and cases with limited space
 Applications requiring quiet operation and semi-passive cooling
Key specifications
 Model: Noctua NF-A4x10 PWM (MPN: NF-A4x10 PWM, EAN: 9010018100440)
 Size: 40 x 10 mm (fan diameter 40 mm)
 Voltage: 12 V
 Speed range: 1000–5000 RPM (max; L.N.A. reduces max to 3700 RPM)
 Airflow: 8.9 m³/h
 Max static pressure: 1.95 mmH2O

 Cabling: 20 cm primary cable, 30 cm sleeved extension, 4-pin PWM, 4-pin Y-cable included
 Warranty & reliability: MTTF \>150,000 hours; 6-year manufacturer's warranty
How to use
Connect the 4-pin PWM connector to a compatible motherboard or fan controller header to enable automatic speed control. If the system requires lower maximum speed, attach the supplied Low-Noise Adaptor to cap the maximum RPM to 3700. Use the OmniJoin adaptor set to adapt the fan to proprietary headers by cutting the original cable and fixing it with the supplied Scotchlok connectors. For longer reach or daisy-chaining a second fan to the same header, use the supplied 30 cm extension cable or the 4-pin Y-cable. Mount the fan using standard screws or clips compatible with 40 mm fans; the integrated anti-vibration pads maintain compatibility with typical heatsink and case mounts.
Usage recommendations
Install the fan so airflow direction matches your cooling layout and ensure the PWM header supports 4-pin speed control to take full advantage of the NE-FD1 IC and semi-passive stop-at-0% functionality. Use the Low-Noise Adaptor when lower maximum speed or reduced acoustic output is preferred.
